65,4x^(4)+7x^(2)-2

4x^(3)-7x^(2)-x-2

Integrate: int x^(2)/(2x^(4) - 7x^(2) - 4) dx

Simplify the following : 5x^(4) - 7x^(2) +8x - 1 +3x^(2) - 9x^(2) + 7 - 3x^(4)+11x - 2 +8x^(2)

If the range of f(x)=(2x^(4)-14x^(2)-8x+49)/(x^(4)-7x^(2)-4x+23) is (a,b] then (a+b) is

If f(x) = 2x^(4) + 5x^(3) -7x^(2) - 4x + 3 then f(x -1) =

The factors of (x ^(4) - 7x ^(2) y ^(2) + y ^(4)) are

Subtract: 7x^(4)-5x^(3)+4x^(2)+3x-3 from 6x^(4)-4x^(3)-8x^(2)-2x+7

Subtract : 2x^(4) - 7x^(2) + 5x + 3 " from " x^(4) - 3x^(3) - 2x^(2) + 3

From the sum of 6x^(4) - 3x^(3) + 7x^(2) - 5x + 1 and -3x^(4) + 5x^(3) - 9x^(2) + 7x - 2 subtract 2x^(4) - 5x^(3) + 2x^(2) - 6x - 8
